The older version of the PPTX file is PPT, which was used in Microsoft PowerPoint 97 through 2003. Note: Microsoft PowerPoint's PPSX format is similar to PPTX except that it will open directly to the presentation while PPTX files open to the editor mode.
Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries.
Atherosclerotic vascular disease -- commonly called atherosclerosis -- is a disease of the blood vessels in which plaque builds up in the lining of the artery walls.hen atherosclerosis affects the arteries of the heart, it is called coronary heart disease. The buildup of plaque inside the coronary arteries limits the flow of blood to the heart muscle.
